Diablo III Patch 1.0.4 Preview: Wizard

Blizzard writes:

"Like the other classes, the wizard is also seeing a lot of tuning improvements to help promote build diversity. Rather than focus on those minor adjustments, though (which you'll be able to learn more about in the 1.0.4 patch notes), I'm going focus the majority of this preview on Hydra."
